Make sure you accept a single parameter of type String in your function declaration - Need help figuring this out!

Hi Jason,

That is not a helpful error message! (Paging Pasan Premaratne)

Turns out the problem is that the challenge asks you to give the parameter an external name of for, and an internal name of location. You only gave a single name, which ends up being used for both internal and external. You have to add the word for before location.

Once that's fixed, it will give another unhelpful error message that you need to return a tuple of type (Double, Double). Again, you're doing that, but your labeling does not follow the instructions. They say not to name the returned tuple values. Simply delete your labels lat: and lon:.

Let me know if you have any questions!

Cheers

// Enter your code below
func coordinates(for location: String) -> (Double, Double) {
    switch location {
    case "Eiffel Tower":
        return (48.8582, 2.2945)
    case "Great Pyramid":
        return (29.9792, 31.1344)
    case "Sydney Opera House":
        return (33.8587, 151.2140)
    default:
        print("error--location not found.")
        return (0, 0)
    }
}
